i ran 115kw at the wheels on a map optimised for the dynodave header, then with the same map, i ran 91kw at the wheels after bolting up the stock dc2r header. The header threw my a:f curve way off though, so with a re-tune, we'd probably have pulled back another 15kw. Still, that leaves a quite a power deficit.

lol

that sounds better :)

Sounds like nice gains though so why did you take off Dave's header then?

dave built it as a development model, after testing it out, he felt there were some areas for improvement... so now he's making a new design.

I don't know but 10KW@wheels is a lot, maybe it's high reading dyno???

Im sure the programeable ECU had a lot to do with it :p

from what i've seen, dyno dynamics shootout mode is pretty darn consistant... plus, the fact that the car pulled 115kw and backed it up with a 14.39@96.24 gives the dyno readout a bit of credibility. so- 10kw loss or gain on that dyno sounds pretty believable to me.

Don't get me wrong man but I just think that gain of 10KW@wheels just for headers is a bit too much, but that's just my opinion, I could be very wrong:)

well, we're talking a header, plus a map to suit it...

yeh 10kw JUST for a headers MAYBE a bit much to believe . BUT with a ECU MAP to suit i would say YES :)

ECU MAP sorry i missed that part, reading to fast, 10KW is possible, my bad...

Just got my budget Mercury 4-2-1 headers from the ceramic coater today, will be fitting it to my car later this week with a cat back 2" press bend straight thru system on my EG Si.
